MILK-CAN'COVER.

SPECIFICATION forming part of Letters Patent No. 546,498, datedSeptember 17, 1895.

Application filed January 2, 1895i To ad whom, t may concern/.1

Be it known that I, LEE STURGES,a citizen of the United States, residingat Chicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Covers for Milk-Cans and in theMethod of Making Them, of which the following is a specification,reference being had to the accompanying drawings, which are made a parthereof, and in wl1ich- Figures l to 5, inclusive, are sections showingthe cover at five successive stages, Fig. 5 showingit completed. Fig. 6is a section of a cover embodying some features of the invention.

One object of the invention is to provide a cover which shall bestronger, more durable, and superior in other respects to covers asheretofore constructed; and another object of the invention is toprovide a method by which the improved cover may be made with' the leastpossible waste of material and at a minimum cost; and to these ends theinvention consists in the features of novelty that are particularlypointed out in the claims hereinafter.

The completed cover, as shown in Fig. 5, has a Haring portion A and acylindrical portion B that are integral, a diaphragm C, l0= cated in thecylindrical portion, and having a marginal ange c,`bent to embrace abead b on the interior of the cylindrical portion, and a handle D, theends of which project beneath the bent margin c of the diaphragm.

The method of making this cover is as follows: The sheet-metal blank isdrawn by dies to the form shown in Fig. l, where A represents the Haringportion, B the cylindrical portion, and C the diaphragm. The next stepin the process is to sever the neck a short distance from the diaphragm,leaving aV portion of the cylindrical portion on the diaphragm to formthe ange c, as shown in Fig. 2. Thediaphragm and its ange are thenredrawn to reduce its external diameter sufficiently to allow it to beforced into the cylindrical portion, as shown in Fig. 3, this being thenext stepin the process. The handle D is then put upon top ofthediaphragm, With its ends touching or close to the ange,

and the fiange and cylinder are then subjected to the action ofbeading-rolls to form the bead b and at the same time bend the flange cover it.

If desired, the handle may be secured without conning its ends beneaththe bead, as shown in Fig. 6.

l. A cover for milk cans havinga seamless flaring portion, a seamlesscylindrical portion integral therewith, a bead on the interior of thecylindrical portion, a diaphragm closing the cylindrical portion andhaving a marginal ange embracing said bead, and a handle having endsprojecting beneath the bent ange of the diaphragm, substantially as setforth.

2. The method of making covers for milk diaphragm from the cylindricalportion and then securing the diaphragm in the cylindrical portion,above the bottom thereof, substantially as set forth.

4. The method of making covers for milk cans which consists in drawingthe blank to a form havinga flaring portion, a cylindrical portion and adiaphragm closing the cylindrical portion, severing the cylindricalportion some distance from the diaphragm, leaving said diaphragm with amarginal flange, redrawing the diaphragm to reduce its diameter to lessthan the interior diameter of the cylindrical portion, and securing thediaphragm in the cylindrical portion, substantially as set forth.

5. The method of making covers for milk cans, which consists in drawingthe blank to a form having a flaring portion, a cylindrical IOO portion,and adiaphragm closing the cylindricylindrical portion and the flange ofthe diacal portion, severingr the cylindrical portion phragm to securethe diaphragm in place, 1o some distance from the diaphragm, leavingsubstantially as set forth.
